The Diamondback™ is the first ball with Activator® Solid coverstock available at the Advanced Performance price point. The original Activator® coverstock used on the Diamondback is a proven formula that provides strong downlane recovery, longevity of ball reaction, and unprecedented durability with superior resistance to cracking. The Diamondback uses the proven Brunswick multisided Rocket™ core system, providing a Low RG core that when combined with the original Activator® coverstock produces a ball reaction that is unmatched at the Advanced Performance price point. Clean through the front with an aggressive move at the breakpoint, the Diamondback gives amazing bang for the buck. There isn't another ball in this class that's even close. With its 2,000 Siaair Micro Pad finish, the Diamondback will provide good length with a strong continuous backend reaction that matches up on medium to oily lane conditions for a wide range of bowling styles. The Diamondback can be drilled using the standard drilling techniques developed for symmetric bowling balls.
